Buying Guide: Best 18650 Battery Charger in 2021

What 18650 Charger to Buy?

You should not want to make a mistake with your buy. That’s why we tell you to take into account some important aspects that can save you time and money.

▷ Power: USB, Car or Electric Network

It is important to consider the type of power that the charger has. Choose one according to the usual place in which it will be used. The best option for its versatility is USB input. We can use adapters for normal 220v plugs. Also, adapters for the car cigarette lighter or even connect it to a computer.

▷ Amperage and Charging Times

The higher the output current of the charger, the less time it takes for the batteries to charge. Although their life is also reduced. A good option is to choose a charger with an adjustable output that allows you to charge regularly at 0.5 amps. And, if necessary, go up to 1 amp to reduce the time.

✓ Battery Capacity

The battery capacity is marked in mAh and does not influence the choice of the charger. This will usually have a 500 mA output for the normal charging process. And sometimes the 1000 mA option for fast charges. Thus, it is important to clarify that any charger for 18650 batteries is valid for such batteries regardless of the capacity they have. Only that the higher the capacity, the longer they take to charge.

▷ Loading Slots

Another important aspect when buying a charger is the number of slots available. If you do not have problems with the size, it is advisable to choose at least 4 slots. Although you generally do not use them. There is always the possibility that in the future you will have to load more units. Or even that one of the slots will break down and you will continue to have others available.

▷ Security Protections

The process of charging a battery always carries certain risks. That is the worst case that can cause an explosion. It is advisable to always choose appliances that have three safety features. They are overhead protection, overload protection, and reverse polarity protection. The price increase is little and it compensates. Good electronic management reduces the possibility of accidents. Also, it extends the life of the batteries.

▷ Best Brands

Although the market is full of different brands and very cheap. In our opinion, the small savings compared to recognized brands do not outweigh the risks. Here is a list of the most experienced and prestigious brands:

• ✓ Nitecore

• ✓ EASTSHINE

• ✓ Efest

• ✓ Snado
